One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. By way of learning-by-doing, we'll look at ROE to gain a better understanding of Henan Mingtai Al.Industrial Co.,Ltd. (SHSE:601677).

Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How Do You Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for Henan Mingtai Al.IndustrialLtd is:

9.6% = CN¥1.4b ÷ CN¥15b (Based on the trailing twelve months to September 2023).

The 'return' refers to a company's earnings over the last year. So, this means that for every CN¥1 of its shareholder's investments, the company generates a profit of CN¥0.10.

Does Henan Mingtai Al.IndustrialLtd Have A Good ROE?

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As you can see in the graphic below, Henan Mingtai Al.IndustrialLtd has a higher ROE than the average (7.5%) in the Metals and Mining industry.

That is a good sign. However, bear in mind that a high ROE doesn't necessarily indicate efficient profit generation. Especially when a firm uses high levels of debt to finance its debt which may boost its ROE but the high leverage puts the company at risk.

The Importance Of Debt To Return On Equity

Virtually all companies need money to invest in the business, to grow profits. That cash can come from issuing shares, retained earnings, or debt. In the case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the use of debt will improve the returns, but will not change the equity. That will make the ROE look better than if no debt was used.

Combining Henan Mingtai Al.IndustrialLtd's Debt And Its 9.6% Return On Equity

Henan Mingtai Al.IndustrialLtd has a debt to equity ratio of just 0.075, which is very low. Although the ROE isn't overly impressive, the debt load is modest, suggesting the business has potential. Careful use of debt to boost returns is often very good for shareholders. However, it could reduce the company's ability to take advantage of future opportunities.

Summary

Return on equity is useful for comparing the quality of different businesses. In our books, the highest quality companies have high return on equity, despite low debt. If two companies have the same ROE, then I would generally prefer the one with less debt.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too.
